normally have their own weapon with .8 attacks per second that gains base damage as they level up. A level 20 skeleton has 1,012 average damage per hit.

The Iron Mass removes the skeletons' attack speed and base weapon damage from leveling up the gem and replaces it with its own damage and attack speed. An Iron Mass with maximum attack speed and damage rolls has 1.53 attacks per second and 195 average damage per hit.

A level 20 skeletons does (1,012 X .8) = 810 DPS

A perfect rolled hidden blade does (195 X 3) = 585 (585 X 1.53) = 895 (Note: Can go higher with corrupted modifiers.)

Scaling Damage

Skeleton damage normally scales with X 1.5 damage and X .8 attack speed. (1.5 X .8) = 120% of raw damage scaling.

Skeletons with The Iron Mass have X 3 = damage and X 1.53 attack speed. (3 X 1.53) = 459% of raw damage scaling.

459 / 120 = 3.825

The Iron Mass gives nearly 4 times the damage per second from flat added damage and the base weapon damage is lower than skeleton damage from the gem at level 22. These 2 factors make added flat damage give higher damage per second than a skeleton build that doesn't use The Iron Mass.

A few examples of flat minion damage may include:
